Hello dear support.
I am facing something interesting - the map in 2D mode looks rather distorted toward the other map providers - Google, Microsoft and OpenStreetMaps…
It’s somewhat like stretched on the width.
Cesium might be using a different map projection than the other service you are looking at. By default, Cesium uses a GeographicProjection. You can try changing it to WebMercator like this:
var viewer = new Cesium.Viewer('cesiumContainer', {
sceneMode : Cesium.SceneMode.SCENE2D,
mapProjection: new Cesium.WebMercatorProjection(Cesium.Ellipsoid.WGS84)
});
